I ordered one of these up about a month back with the intent of adding 
some meaningful support for the device, but have been too busy with work 
and other things. I honestly didn't take it out of the shipping pouch 
until just now. If you want, I can create a new component on trac, and 
assign myself the owner. I'll be out of town for work until late in the 
month, but can look at it when I get home.

There's little reason to even enable CEC at the moment, as the only 
thing MythTV allows at current is to send a power toggle to the first TV 
it finds on the bus. I'm intending to set up some form of graphical 
mapping through the frontend Services API to allow easier definition of 
devices and behaviors, but have no idea when I might get around to that.
